In the past, Web2 was known as the "data" world, where every service could convert user behavior into data. However, Web3 is transforming this data into "assets" through blockchain technology. When data becomes an asset, the focus shifts to the value that these assets can create, rather than the limitations of having personal data stored on servers owned by others. This is why many Web2 companies heavily rely on advertising and data to generate revenue, as data is their valuable asset.
